The filings come as Trump's campaign
scrambles to hire ground staff to compete with the sprawling
operation of his rival for the White House, presumptive
Democratic nominee Hillary Clinton.

Clinton's team said it raised $28 million in May through the
campaign and its "victory fund," finishing the month with $42.5
million on hand. Clinton has
poured millions of dollars into television advertisements
this month in crucial swing states like Ohio, Florida, and
Nevada.

Trump has yet to air a television advertisement since becoming
his party's presumptive nominee in May. He has just
70 people on his staff, compared with Clinton's 700.

And he fired his controversial campaign manager Corey Lewandowski
earlier
Monday, underscoring the concerns Republican leaders have
about Trump's chances in November.

Both candidates are off the pace of last election's candidates.
In
May 2012, Republican candidate Mitt Romney's campaign raised
$76.8 million, while Barack Obama's campaign raised $60 million
in the president's reelection effort. Both sides had more than
$100 million on hand at the end of the month.

Trump repeatedly stated throughout the Republican primary season
that he would self-fund his campaign, but the Manhattan
businessman reversed course in March by saying he would raise
money for the general-election fight.

He set a fund-raising goal of $1 billion
in May, though he
backtracked on the vow a month later.
